It sounds similar to PatPat - I bought a load of maternity clothes and they were horrible, cheap quality compared to the photos. You can't just return them, you have to get in touch and tell them you want to return your clothes, and why, and send photos. They were happy with my reason, said they didn't want me to have to go to the hassel of sending them back and gave me a full refund, that's how cheaply they make their clothes!I ordered some ITS stuff just after Christmas (was in the top scale of my comfortable weight and needed so looser clothes to wear).
Ordered £80 odd worth of clothes, returned one thing and they refunded the full amount.
They make enough money from selling shite that it didn’t even cross my mind to tell them their mistake and allow them to correct it
ITS probably gave you a full refund on purpose so you come back to them
